Psalms 31:2-3

Be thou&c. Lit. Become(LXX γενοῦ) to me a stronghold-rock, a fortress-house to save me: for(he goes on to give the ground of his prayer) thou art my cliff and my fortress: i.e. prove Thyself to be what I know Thou art. "It is the logic of every believing prayer." Delitzsch. For the figures see note on Psalms 18:2.

therefore&c. And for thy name's sake thou wilt lead me and guide me. A further expression of trust rather than a petition. By gentle and unerring guidance God will shew Himself all that He has declared Himself to be. Cp. the same words in Psalms 23:2; Psalms 3, and see notes there.
